this is great but..

I was able to save the first image to my Photos library, but I cannot save any subsequent images. The “Save Image” option does not save them to Photos.

I can still save the images to Files. Sketch Clean has Full Access to Photos, and restarting the app did not fix the problem.

Could you please help me resolve this issue?

Thank you.

Waste of $$

It doesn’t clean up the lines just turns the image into an svg.
